Very good and detailed instructable.Since I am in Germany and we don´t have SYP boards I used pine terrace flooring boards and pince constructions board. Since the boards have different width and thickness i had to change some measurements. But it still worked out great!I made it for my wife as a surprise, and she was thrilled.I have very limited woodworking experience and still could pull it off thanks to the great and detailed instructions. And I learned a lot.THANK YOU!
